Mawile EX = Mawile V
Mega Mawile = Mawile Vstar
Mawile Vstar usually cant do enough damage on it's own, thats why garbodor is in the deck. Galar mine is supposed to trap your opponents active pokemon, since we play 10 switching cards (for mawiles attack).
Radiant Gardevoir and Big Charm can get your Mawile up to 310 hp, and Espeon Vmax and galarian articuno are both backup attackers.
Zacian V and cresselia accelerate energy, but they can both be backup attackers.
